Dog Food Ingredients A to Z: Zinc

Share Button

Collage of products containing zincWow!  Today, at last, we have reached the end of the alphabet in our “Ingredients A to Z” series.


Today’s letter is Z and our ingredient is Zinc.  Including today, we have written 27 A to Z ingredient posts (we did two consecutive posts on the letter M due to a reader request).


This has been a fun and educational series for us (and hopefully for you the reader also).   And we are not planning to stop anytime soon, we plan to start again at the letter A and plow through the ingredient list, letter by letter for as long as it takes to evaluate the most common, if not all, ingredients in dog food.


With that said, let’s look at Zinc and why it is important (or not) for your dog’s health.


What is Zinc?

Zinc is an essential trace mineral that is required in a dog’s diet to maintain good health.  It is concentrated in certain parts of the brain, pancreas, and adrenal glands, as well as being present in the nucleus of all cells.


Natural sources of Zinc include red meats, seafood (especially oysters), spinach, pumpkin, chicken, pork and mushrooms.


Common names for Zinc

The most commonly used names in dog food include Zinc Chelate, Zinc Methionine, Zinc Oxide, and Zinc Proteinate   Note that Zinc Oxide is a poorly absorbed version of Zinc and is indicative of a lower quality food.


Why is Zinc included in dog food?

Zinc is an essential mineral and is involved in more metabolic reaction (cellular level reactions required to sustain the body function) than any other trace mineral.


Is Zinc a commonly used ingredient in dog food?

Zinc in some form is an ingredient in a whopping 92% of all dog food.


Common benefits or risks of Zinc

Zinc is critical in the structure and function of cell membranes and supports a healthy immune response to disease.

Zinc helps with protein and carbohydrate metabolism and can support a healthy liver.

Zinc helps the skin function and wound healing.

Proper zinc levels are required for a normal reproductive function.


Miscellaneous facts about Zinc

Corn, wheat, rice, and soy can all interfere with the body’s ability to properly absorb Zinc.

Zinc deficiency affects about two billion people in the developing world and is associated with many diseases. In children it can cause growth retardation, delayed sexual maturation, infection susceptibility, and diarrhea, contributing to the death of about 800,000 children worldwide per year.

  2. Mom takes Zinc if she has or is getting a cold. She used to take it daily but it makes her sick if she hasn’t eaten enough first, so she quit that habit. I guess it is good for us furry ones too. Now the alphabet is done…what next?
